nvptx plugin: do not force JIT target SM version
    
When link_ptx runs, a CUDA device is already bound to current thread, so the
driver library knows the target architecture.  There isn't any benefit from
forcing a specific target here; on the contrary, hardcoding sm_30 breaks
offloading on later (Maxwell, sm_5x) devices.
    
	* plugin/plugin-nvptx.c (link_ptx): Do not set CU_JIT_TARGET.
